Description

A portable object for regatta {PORTABLE OBJECT FOR REGATTAS}

The present invention relates to a race start support method for a boat participating in a regatta. The invention also relates to a device implementing the method.

In a regatta race, the boats must not cross the start line before the start signal, otherwise the boats must turn and cross the start line again.

The start line may be defined by the position coordinates of two points defining a virtual line.

In these regatta races, the goal is not only to first cross the start line in accordance with the start signal, but also to cross at the speed closest to the maximum speed of the boat.

In a regatta race, participants perform a pre-start that takes place five minutes before the start signal for adjustment to cross the start line in an optimal way.

Means for generating a virtual start line, means for instantly recognizing the position of the boat with respect to the virtual line, means for recognizing the instantaneous speed of the boat, and means for calculating the distance to the virtual start line and the time remaining until the start signal There is a known support device for crossing the start line.

Using this knowledge of the remaining distance and time remaining, the boat must adjust the speed of the boat to cross the line, which causes the captain of the boat to make many choices and leave uncertainties as a result.

If the captain needs to adjust the boat to adapt to this information, it will affect the start.

It is an object of the present invention to provide a product and a method of operation that provide a simpler and more reliable way of managing the start of a regatta while maintaining an intuitive state.

To this end, the present invention relates to a method for supporting a race start for a boat participating in a regatta including a pre-race with a duration (T) before the start line crossing, To generate at least one indication of how to proceed in the race, the creation and storage of a virtual type of start line, and the determination of the position of the boat relative to the start line and the instantaneous speed of the boat, The method comprising the steps of:

In the second step, before the race, at least one race start is measured and stored at least once, the parameter being the maximum speed of the boat (Vm) or test speed, and from there, if the boat has moved to the test speed, Is simulated by performing a pre-race test to derive the maximum distance D that can be moved, thereby determining the position of the line L called the maximum distance line;

In the third step, after positioning the boat between the maximum distance line and the start line, the countdown cycle is started while the distance line is moving toward the start line at the test speed, on the one hand, On the other hand, the actual motion parameters of the boat, when the distance line follows the boat, the boat moves at the same speed as the distance line The boat is compared with the movement of the distance line to provide indications of the proximity of the distance line to the boat to enable the boat to adjust the speed and / or the route of the boat.

In a first preferred embodiment, during the second phase, the maximum speed is stored several times, and the maximum speed of the distance line is the average of the stored maximum speeds.

In a second preferred embodiment, the indications for the method of proceeding exist in digital form or in a visual form.

The present invention relates to a race start support device for a boat participating in a regatta comprising means for inputting information regarding a start line position to a calculator, satellite positioning means, storage means, calculator and / or storage means,

The device comprises means for predetermining a maximum test speed, means for calculating a separation distance corresponding to the calculated maximum speed multiplied by the time corresponding to the duration of the pre-race, Means for comparing the speed and position of the boat with respect to movement of the distance line, means for providing a representation of the difference in speed and / or distance between the boat and the distance line, and display means .

In a first preferred embodiment, the device comprises means for calculating the evolution of the speed of the boat so that the motion of the boat coincides with the motion optimized for the start line to be crossed.

In a second preferred embodiment, the device is integrated into a portable object, such as a mobile phone or tablet.

In a third preferred embodiment, the device is incorporated into a clock.

In a fourth preferred embodiment, the display means is digital or visual.

In another preferred embodiment, the crystal of the watch is touch sensitive.

The invention will be clearly understood with the aid of the following description given by way of a non-limiting example with reference to the drawings, in which: Fig.
1 is a view showing a water line showing a start line and a boat;
2 is a schematic diagram illustrating a support device for a regatta;
Figures 3 and 3B show a water line showing a distance line with a maximum distance from the start line.
Fig. 4 is a view showing the water area of Fig. 1 in which the countdown has been started; Fig.
Figure 5 shows the water of Figure 1, with the boat moving at the same speed as the distance line;
6 illustrates a clock fitted to a support device;
Figure 7 illustrates an alternate embodiment of a watch fitted with a support device;

Referring to the various figures, the body of water for a boat regatta is illustrated.

Figure 1 shows a start line 2 whose coordinates can be determined from two geographical points (A, B), for example data provided by geostationary satellites. A boat 1 to cross the start line 2 is also exemplified.

The start of regatta is an important moment. In fact, boats must cross the start line at the highest speed after the start signal, since the start line must be crossed before the start signal, the participant must turn and then cross the line again in the right direction.

In addition, if a player drops his speed very abruptly to avoid crossing the line too quickly, he will need time to regain speed and start a sluggish start.

Accordingly, the portable device 100 using the race start support method for the boat participating in the regatta is used.

The portable device 100 shown in FIG. 2 will include a calculator 10 for overall control of the portable device. The portable device 100 further includes satellite positioning means 11, storage means 12 for storing data, and means 13 for inputting information about the start line position to the calculator and / or memory. The means 13 may be one or more buttons or touch sensitive means.

These means may be supplemented by means 14 for predetermining the maximum test speed that associates the time base with the positioning device, for example, to determine the speed. However, it is also possible that the speed is obtained from an external device.

The calculator 10, which may be a microprocessor or microcontroller, comprises means 10A for calculating a separation distance corresponding to the calculated maximum speed multiplied by a time T corresponding to the duration of the pre-race, a test speed Vm, Means for comparing the velocity and position of the boat with respect to the motion of the distance line L and means for comparing the velocity difference and the position of the boat with respect to the distance between the boat and the distance line, And means 17 for providing indicia.

Means for calculating the development of the speed of the boat so that the motion of the boat corresponds to the motion optimized for the start line to be crossed, and display means (19).

During the first step shown in Figure 1, the geographic points forming the start line are stored in the object. These geographic points may be manually entered or may be downloaded or stored by pressing the button of the portable object to position itself on the point on the start line using the GPS device and to store the position. The operation is repeated to obtain the second point to describe the start line.

The method then includes a second stage or preliminary stage with a duration T.

During this second step, shown in FIG. 3, at least one race start is simulated via the speed determining means 14 to measure and store the parameter at least once, which is the maximum speed Vm of the boat or the "test speed ". This simulation takes the form of a pre-race test under actual conditions. This velocity information is used to calculate the maximum separation distance D that can be shifted during the pre-race duration T if the boat has moved at the test speed and thereby determine the position of the means 10A ). This distance D is stored by the calculator 10 via the storage means 12. [ The latter may be a flash memory.

In the third step or race start phase, the boat 1 is positioned between the maximum distance line L and the start line 2. The countdown with duration T is then started.

During this countdown, the calculator moves the distance line L toward the start line at test speed Vm, as can be seen in Figs.

Using the calculator, the position and / or actual motion parameters of the boat 1 are compared with the movement of the distance line L. [ In fact, the boat may be stopped or slightly moving.

The calculator 10 thus provides indications of the proximity of the distance line L to the boat 1 in order to enable the boat 1 to adjust its speed V and / do. This makes it possible for the boat 1 to move at the same speed as the distance line when the distance line catches the boat 1.

As a result, as time progresses, the boat 1 will be accelerated and the distance line L will move closer to the boat. The difference in speeds will be limited by the distance between the distance line and the boat 1. The parameters can therefore be calculated to allow the boat to evolve the speed and / or the route of the boat 1 so that the motion of the boat is consistent with the movement of the distance line L before crossing the start line 2 .

It will be appreciated that measurements of various measurements, such as the distance between the boat 1 and the start line 2, take into account the relative position of the boat. In fact, depending on the wind direction, the boat 1 may not always be navigating in a straight line.

This fact implies the existence of actual distance and relative distance. The actual distance d1 is the shortest distance between the boat 1 and the start line 2 while the relative distance d2 is the distance between the boat 1 and the start line 2 considering the direction of the boat. The actual distance d1 passes through a line perpendicular to the start line 2. The relative distance d2 is calculated by determining the angle alpha between the line perpendicular to the start line 2 which is the actual distance d1 and the straight line formed by the direction of the boat as seen in Figure 3b, d2 = d1 / cos?

As a result, the calculator 10 can determine the actual distance d1 and the relative distance d2 depending on the position and direction of the boat 1. Since the relative distance is variable due to the angle alpha and the relative distance is unstable, the boat 1 can be tacked so that the actual distance remains stable. Therefore, in the case of the start of the regatta, Will be understood. The purpose is to determine the speed and position of the boat 1 in such a manner that the movement end of the boat during the pre-race expresses an optimized crossing of the start line 2 in relation to both the distance from the start line 2 and the speed To coincide with the movement of the distance line (L).

To achieve this, the device provides the boat 1 with information, e.g., differences in speeds, distance between the distance line L and the position of the boat 1, and predicted speed change commands.

This information is provided by the information means 20 and the display means 19. The information means 20 may take the form of digital representations, such as numbers, or take the form of visual indicia, such as clock hands 22, which move with respect to the display lights 21 or the scale line.

Preferably, the information is presented in the form of visual indications. In fact, these visual indications are easier to understand when considering that the boat operator has other tasks to process. For example, the display lights may be slowly illuminated or colors may be used.

When colors are used, one example may include a plurality of display lights in the form of segments. These display lights may be different colors, and the colors are associated with information of a particular piece.

In the example of the present invention shown in Fig. 6, eleven display lights are provided in the portable object. Specifically, there will be five display lights having the first color 21a, one display light having the second color 21b and five display lights having the third color 21c.

When the countdown is started, five display lights having the first color 21a are illuminated. The first color may be red. When the distance line L moves closer, as the distance line L becomes closer, some display lights will turn off so that the number of illuminated display lights 21a decreases. At that moment, the boat 1 is accelerated.

When the distance line L follows the boat 1 and the speed of the distance line L is close to the speed of the boat 1, the display light with the second color 21b will be turned on. The second color may be green. This means that the boat 1 is in the optimum phase, i.e. at the correct distance and at the correct speed for crossing the start line 2 in an optimal way.

When the display lights having the third color 21c start to turn on, this means that the boat is in front of the distance line L and must decelerate. The third color may be orange.

Thus, by left-right apportionment, it is possible to indicate according to the illuminated color whether the boat 1 is in front of, coincident with or behind its motion curve. The captain is able to recognize whether he is in front of the required timing (orange), behind (red) or within (green).

This also makes it possible to indicate whether the boat is significantly ahead or behind by the number of illuminated display lights 21.

Of course it is possible to anticipate display lights taking the form of three bars of different colors each. The bars indicating whether the boat is in front or behind are then formed by a plurality of zones so that the more the boat is before or behind the boat, the greater the number of illuminated zones.

These means are included in a cover of a portable object such as a telephone, tablet or watch case.

The motion speed of the boat 1 can be obtained by GPS type satellite positioning. It also makes it possible to store the maximum speed by pressing the clock's button or the phone's keyboard. It is also possible to obtain this speed using an external sensor.

Thus, the device may include a dial containing a clock hands 22A, indicating that, at 12 o'clock position, the difference between the instantaneous velocity and the distance line velocity is equal to zero, as shown in Fig. If the clock eye moves to the right on the ruler 22B, this means that the instantaneous velocity is greater than the distance line velocity and therefore needs to be slowed down, which means that if the hands move to the left, the instantaneous velocity is insufficient . The amplitude of each motion gives the idea of the importance of the difference, and it is also possible to arrange the clock hands, for example, towards an explicit pictogram representing a - sign or a + sign.

The second clock hands 22C may represent a distance that separates the distance line from the boat on the scale line 22D, such as the above-described clock hands.

Instead of clock hands, there may be pie-shaped segments.

Considering that the simulation occurs before the race, the weather conditions can be considered by calculating the average of the various tests. This average can be affected by the correction measures depending on the wind speed measured at the time of the race. The maximum speed of the distance line may be an average of several simulations.

It will be apparent to those skilled in the art that various changes and / or improvements and / or combinations obvious to those skilled in the art may be made to the various embodiments of the invention described above without departing from the scope of the invention as defined by the appended claims.

The storage means 12 may be a rewritable semiconductor mass memory utilizing NOR or NAND technology.

In addition, the present invention should not be limited to portable products such as phones, tablets or watch cases, but may also be a bracelet or laptop computer.
